Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2).-Wikipedia
As I am writing this blog post, more than 6,63,000 people have been confirmed infected world wide, it of which, more than 1,42,000 are now totally recovered and there has been more than 30,000 deaths. We can say that this disease (COVID-19) has become a pandemic. In many countries it has reached stage 3. The stages of the spread of disease are-
Stage 1- Where the authorities know who came from the affected countries and those persons should be quarantined and kept under watch for signs of disease.
Stage 2- Where the people migrating from affected countries come in contact with local people, like family members, friends, relatives or various service people but still the authorities can track those who came in contact with the migrants from affected countries.
Stage 3- Now the local people who came in contact with the migrants from affected countries mingling with other local people. Here because of the large scale of interactions the authorities cannot track the spread of infection and hence everyone is a suspect of infection.
Now let's have some thought about the virus.
What is a virus?
Virus is not actually a living thing. It is just like a computer virus. It only works when conditions are favorable.
A virus on it's own don't shows any signs of life, it doesn't consume food, doesn't make any energy, there is no chemical reaction happening inside, there is no movement, no breathing, nothing.
A virus generally is just an RNA (Ribo Nucleic Acid) which contains the generic codes for reproduction, some enzymes which helps in starting the reproduction process, these two are packed in a protein and lipid envelop. This protein envelop has some special proteins which acts as key to enter the host cell.
If there is a pen drive, which contains a computer virus capable of infecting windows 10 through some weak points of windows 10, and we keep the pen drive in a closet, then nothing will happen until we plug the pen drive in a powered on PC with Windows 10 operating system. If the virus I is plugged to a Windows 10 pc which is powered on then only the virus will get activated and start infecting the PC, then if there is an antivirus installed which recognises the activity of the virus then there are 2 cases 1) the virus may have capacity to overpower the antivirus program, in this case the virus will cause harm, make copies of itself in all connected devises or 2) the antivirus successfully deletes the virus files and there will be the end of the virus.
If we plug the pen drive in some Apple device then there will be no activation of the virus at all.
Similarly natural virus has these particular key proteins in it's envelop which opens the door of the host cell. That is every living organism has different proteins supported by cholesterol in it's cell membranes which only allows the required molecules to enter into the cell. These key proteins in the virus envelop are very particular about the host cell, for example HIV can only infect human lymphocytes, not any other cell or not the lymphocytes of a dog.
Once the virus key proteins opens the lock of the host cell door, a passive entry of the enzymes and RNA in the the host cell is triggered. The enzyme and RNA then quickly starts synthesizing the proteins necessary for making the virus copieas by using the cell machinery. The cell now become a zombie, it doesn't now perform it's intended role but instead starts acting as a virus factory. When the cell becomes full of virus copies, a self destruct mechanism gets triggered, which destroys the host cell, releasing the viruses. The new viruses released, starts infecting more cells, each one of them produce many more viruses. Now the infected person can spread the infection through his body fluids like cough(mucus)/saliva/urine/feces/blood/genital fluids as per the infection. (Cough/saliva in the case of COVID-19, which gets sprayed when the infected person coughs or sneezes. This virus is heavy, so it doesn't float in the air, it falls down and remains on the surfaces in the vicinity of the infected, when a healthy person touches such surface, it picks up the virus and if the person touches it's nose/eyes/mouth with such dirty hands without washing then the virus reaches it's destination and starts infecting.)
Now the virus defence is done by our immune system by various ways like- killing such infected cells and stopping the reproduction of the virus or making antibodies which binds to the virus envelop which prevents the virus from entering any cells i.e. our cells now recognise it as a foreign body and don't allow it to enter the cell.
This particular Novel Corona Virus infects our respiratory tract lining cells which causes dry cough, fever etc.
Now there is some time gap between the entry of the virus in our system and experiencing the symptoms of the disease. This period is called the incubation period. That is the person is infected but doesn't show the symptoms of the disease. To understand this incubation period let's take an example of Terrorists vs Nation-
Suppose a handful of Terrorists enter a nation with an intention of creating a terrorist organization by recruiting the citizens of the same nation, brainwashing them, training them and then using them against the same nation. You can understand that this process will take time before it starts showing it's existence. At first no one will notice the terrorist, the terrorist will then try to recruit, brain wash, train the members; till then some good citizen will notice that something bad is going on, he will raise the alarm, but the security system of the nation will also be sceptical about the alarm so it will just inform a local patrol to check it out, and then when the local patrol will confirm the situation, a countermeasure will be taken, it may involve a limited attack if the situation is not severe, but if it's too late then emergency will be declared in the nation and all the resources of the nation will be used to defend the nation from the terrorist threat. All of the normal public of the nation will only suffer if emergency is declared otherwise it will be a local affair.
In the same way, if things go too out of hand then only our immune system declares an emergency, all the resources of our body are diverted towards our immune response, that is, all energy is diverted towards the immune cells, all other gets less energy, hence we feel weakness, all other processes are slowed down e.g. digestion, hence we feel nausea, nose starts running, more cough is produced to flush out the infection, temperature of the body is raised to help our immune system function more effectively. We call all these, symptoms.
What will happen next?
There are two possible conditions-
1) Positive case- The spread of the disease will soon be contained, the number of the people getting detected COVID-19 positive will start decreasing. And it will end soon.
COVID-19 vaccine trials get successful and we don't have to fear it anymore, all the life returns to normal in a month.
2) Negative case (Worst case)- The disease keeps on spreading rapidly, exponentially. Almost all the population on the Earth will get infected, but is it the end of the mankind? Is it where all ends?
Certainly not.
Law of natural selection / survival of the fittest :
We all have learnt the law of natural selection, the one who is fit to survive in an environment survives, others who can't- die. This is the nature's way of weeding out the weak ones.
There has been many such natural disasters in the past like, ice age, droughts, floods, tornadoes, meteor strike, many epidemics, pandemics etc. But still the life thrive. Because the survivers are stronger and they quickly take up the vacant places.
This period is the live demonstration of natural selection / survival of the fittest.
We are observing a history in the making. We will tell the tales of how we survived the COVID-19 pandemic, the lockdown period etc. to our children and grandchildren.
Not everyone who is infected by Novel Corona Virus dies, many have recovered totally and many will. The mortality rate is much less than 10% globally.
So what we should do?
Preventive measures prescribed by Government of India-
PREVENTION
But on top of that one should try to keep his or her immune system healthy by-
1) Eating healthy food- Eat home cooked natural food, prefer protein rich and low carb food, practice periodic fasting like eating only once in a day and only water otherwise for the rest of the day-once or twice a week (do check what suits you).
2) Exercise- Exercise 2-3 times a week(more is not needed), exercise is something which pushes you a little(not more, otherwise you would damage something more and never return to exercise) beyond your normal capacity. Exercise should include yoga, cardio and strength.
3) Rest- proper and enough rest is very very important for our immune system. Deep sleep is the best rest. Always take required amount of sleep, listen to your body to determine how much sleep you need, because there are no standards, every body has different needs. For example I need 9 hours of sleep every day, 2-3 hrs less sleep in a week leads to symptoms of infection. Whereas some of my friends need only 5-6 hrs of sleep every day. If you catch any infection and show any symptoms like cough, cold, fever etc. do sleep much more than normal till you get well. When we sleep, almost all of our energy is used to fight the infection and we recover soon. But if we keep working then our immune system gets less energy and you can imagine what will be the results.
What should we do for our wealth in view of the COVID-19 ??
I am an eternal optimist, all global share market indices are down 20-40%. So I think it's a great opportunity to purchase great businesses at discounted prices. Creat a diversified portfolio of great businesses. You can directly buy individual stocks if you understand what you are doing, or can buy index ETF (Exchange Traded Funds), or if you don't understand that much, you can buy a diversified mutual fund of a reputed fund house or an index fund of a reputed fund house. Invest your money in a staggered manner so that if market guess up from here, you have something invested and if it falls further, you will have money to invest. Such opportunity comes only once or twice a decade so don't let it go.
What should we do for our happiness in view of the COVID-19 ?
Many are ordered to work from home (WFH) by their employers, so make the best of it, your travel time is saved, invest this time in the family. Spend quality time with your family. Spend time on your hobbies. Learn something online, cook, paint, sing, dance, do what you like and enjoy. Do remember-
The POWER is when,
You use ODDS,To get EVEN.
So have a nice day.
Sumit,
The POWER is when,
You use ODDS,
To get EVEN.
